Instrumentation circuits

Diode Arrays Procurement Notes

Verify the ordering suffix 'G' confirms Pb-free, Halogen-free, and BFR-free compliance as specified in the datasheet. Ensure the package matches the TO-247 (CASE 340AL) mechanical outline. Confirm that the application requirements align with the 45 V reverse voltage and 40 A total current ratings before procurement.

Diode Arrays Selection Notes

Select this component for low-voltage, high-frequency switching applications requiring high efficiency. The TO-247 package offers low thermal resistance suitable for high-power dissipation. Consider the 175°C junction temperature capability for environments with elevated case temperatures or limited airflow compared to standard 150°C rated devices.

Diode Arrays Part Context

This part belongs to the Switch Mode Power Rectifier family from onsemi. It utilizes Schottky barrier technology to achieve fast switching speeds and negligible reverse recovery charge. The dual-diode design simplifies circuit layouts for synchronous rectification or free-wheeling topologies in DC-DC converters.

Diode Arrays Replacement Considerations

Cross-reference with other 40 A, 45 V dual Schottky rectifiers in the TO-247 package. Verify equivalent forward voltage drops and thermal resistance values to ensure compatibility with existing heat sink designs and electrical performance targets.
